Who it fits
Good fit for
You should consider this motherboard if you are building a compact PC using Intel Core Ultra processors. The Micro ATX form factor fits smaller cases while still offering robust memory support. If you plan to use high-speed DDR5 modules or need the bandwidth of a PCIe Gen5 storage drive, this board provides the necessary lanes. The Wi-Fi 6E module also suits users who want reliable wireless performance without adding separate cards.
Who should skip it
You might want to look elsewhere if you are not using Intel Core Ultra processors, as this board requires the LGA1851 socket. It is also not ideal if you need a full-sized ATX board for extensive expansion, since this is a Micro ATX model with fewer slots. Additionally, if you prefer analog audio connections over digital outputs, note that it relies on a Realtek ALC1220 codec with Nahimic audio software rather than premium discrete audio hardware.
Verdict: This Micro ATX motherboard offers strong support for Intel Core Ultra systems with high-speed DDR5 and PCIe Gen5 storage. It is a solid choice for compact builds that need modern connectivity.

This wireless standard provides faster and more reliable connections. It uses the 6 GHz band to reduce interference from other devices. You will experience lower latency during gaming and video calls. It is compatible with older Wi-Fi 6 and Wi-Fi 5 networks. This feature eliminates the need for Ethernet cables for basic connectivity, keeping your setup clean.
Design and Build Overview
According to the listing, this ASRock motherboard uses a Micro ATX form factor. The model number is B860M Pro RS WiFi. The physical dimensions listed are 2 inches, 3.94 inches, and 9.61 inches. This compact size means it fits into smaller computer cases where space is limited. You will save room for other components or improve airflow in tight builds.
The board features a multicolor finish. This aesthetic choice allows it to blend with various case interiors or stand out depending on your lighting setup. The listing does not specify the exact materials used for the heatsinks or PCB layers. You should assume standard industry practices for a board in this category unless stated otherwise. The layout is designed for the LGA1851 socket, which houses Intel Core Ultra processors.
Controls and connectivity are integrated directly into the board. There are no external physical switches or buttons mentioned in the data. The design relies on standard onboard headers for fans and USB ports. The inclusion of WiFi 6E support is built into the PCB layout. This means you do not need a separate expansion card for wireless connectivity. The compact design keeps the footprint small while retaining essential modern features for a functional desktop build.
Setup And Daily Use Guide
Setting up this motherboard requires an Intel Core Ultra processor, as the LGA1851 socket is exclusive to that lineup. You must install DDR5 memory modules into the four DIMM slots. The listing notes support for speeds up to 8666 MHz when overclocking is enabled. You should ensure your RAM kit is compatible with these high frequencies for optimal performance. Storage expansion relies on the M.2 slots, which support PCIe Gen 5 x4 speeds. This allows for rapid data transfer rates if you use compatible NVMe drives. For display output, you will use the single HDMI and DisplayPort connectors on the rear I/O panel. These ports connect directly to the graphics capabilities of your installed CPU. Audio is handled by the Realtek ALC1220 codec, providing 7.1 channel HD sound. This setup supports Nahimic Audio software for enhanced sound processing. Wireless connectivity is provided by the integrated Wi-Fi 6E module. This standard offers faster speeds and less interference compared to older Wi-Fi versions, especially in the 6 GHz band. Ethernet connectivity is also included, though specific speeds are not listed here. The Micro ATX form factor keeps the build compact, fitting into smaller cases. This size limits the number of expansion slots but simplifies cable management for standard builds. Daily use involves standard operating system installation and driver updates from the ASRock website. The BIOS Flashback feature allows for easy updates without a CPU installed, simplifying future maintenance.
Before You Buy This Board
You need an Intel Core Ultra processor to use this LGA1851 socket. Older Intel chips will not fit. You must buy DDR5 memory separately. The listing supports speeds up to 8666 MHz, but you need compatible RAM to reach those numbers. You also need a case that fits Micro ATX boards. This form factor is smaller than standard ATX. Check your case dimensions carefully. You should install a graphics card if you do not have integrated graphics. The board has HDMI and DisplayPort outputs. You may need a discrete GPU for gaming. You should keep your BIOS updated for new CPU support. This board sits alongside other LGA1851 options. It offers WiFi 6E and PCIe 5.0 storage. Compare it with ATX models if you need more expansion slots. Consider the size constraints before ordering.
Check before you buy
- Verify you have an Intel Core Ultra CPU.
- Check that your case fits Micro ATX boards.
- Ensure you have DDR5 memory modules ready.
- Confirm your graphics card fits the PCIe slots.
